We like to add lots of um features.

We have a problem in that we cannot duplicate the 10-20, which did not appear in our testing. My guess is that it is a difference between installed software version and saved software version, but which versions trigger it is unknown.

We'll consider adding system saves to a future version. There is a possible issue here in that system info is not always portable between software versions (This is why you are recommended to clear setup when upgrading).
